Air Transducer Ultrasonic Level Measurement

The Air Transducer measures solid levels up to 33 ft in range. It has two SPDT relays and a 4-20mA output, and uses “Echo Logic” algorithms and a special piezoelectric crystal to produce “the perfect echo” with a 3° effective beam angle. It has two RS-485 Modbus RTU communication ports for networking in tank farm applications with remote HMI display.ECHO Process Instrumentation Inc., Shalimar, FL 850-609-1777 www.echopi.com
